This SHOULD be the final version of this custom story. What is changed in version 1.2:

- Added Slovak translation
- Removed voiceacting (but its included and can be used if its not hurting your ears)
- 1 new optional area in chapter 4- fixed EVIL ENDING- fixed cutscene bug after final boss defeat- You can now read cutscene text in ENTERTAINMENT HOUSE much better.- Some glitch/bug removal- Fixed TOO loud music in some areas- Some OTHER things...

I will be making videos on this story because it just looks so amazing here is the link to my channel-https://www.youtube.com/channel/UC3m_PIZGHefBS7WI635VI3Q- I think the videos will be out from some time between tomorrow and Saturday

That is not my model, I am not really sure why is that happening but if you load other mod with that furniture piece, it will do the same. I would rather contact the creator of that furniture to fix it but I guess he is no longer active developer. But that is only my guess.

He's asking if there's an automatic [.exe] installer to automatically install the custom story for you, but you have the answer. Modding Amnesia is easy.
EDIT: Then again, he might be asking how to install both the 1.2 and 1.3 versions together, I would like to know also.

I do not know why would he need an .exe installer
when simple moving the files is so easy. Maybe what he wanted to say is that he does not have a winrar on his PC.

"Then again, he might be asking how to install both the 1.2 and 1.3 versions together, I would like to know also."

Well the answer is simple, if you have 1.3, all features of 1.2 are included in there except the fact that this mod was made for 1.2, and 1.3 is breaking some stuff in there.

How to have both versions separately is also simple, if you have non-steam installation folder, you take a copy of your 1.0 version (before applying any upgrade) and install the 1.2 Justine patch to one of them and you apply 1.3 machine for pigs patch to the other one.

I have about 5 Amnesia installation folders just for testing purposes to see which version does what with the content. I also have it on the Steam but I havent played the game for a while.

No, all my mods are supported for both Steam and non-Steam versions. Current problem with steam is that the Steam users
have problems with launching full conversion mods
(from myself those would be META, MANA and Destiny Revenant)
But there are known solutions for solving that.
